Calcareous bands, 
Sandstone of the millstone grit series, cel- 
lular, and carbonaceous. 
Shales, including eight inches of coal. 
The subjoined is an 
approximate section of 
the order of superposi- 
tion of the different beds 
from the sandstones, in 
the ridge south-east of 
Fayetteville, to the black 
shale, with carbonate of 
iron, at the Lick, 1 mile 
west of town. The ex- 
act thickness of each of 
the members I am una- 
ble to give, until more 
accurate measurements 
and levels are taken to 
the outcrop of the differ- 
ent members, and correc- 
tion for dip calculated ; 
for the present, most of 
the thicknesses are given 
by computation from ob- 
servations at different lo- 
calities, rather than from 
‘actual measurements at 
one locality. But, we 
hope, hereafter, to have 
an opportunity of sub- 
mitting a more complete 
section, in detail, with 
the absolute thickness of 
the beds. 
The sandstones, that 
form the upper portion 
of this section, contain 
some remarkable and 
very curious impressions, 
composed of subcylin- 
drical branches, radia- 
ting from a centre, bear- 
ing a distant resem- 
blance to some fossil
